The cycle $A BC D$ of Figure 3.65 is drawn on a $V$ - $T$ diagram: $A B$ and $C D$ are horizontal (constant $T$ ), $BC$ and $D A$ are vertical (constant $V$ ). Its $P V$ diagram consists of:

Options:

Answer:

Solution:

$A B$ is an isothermal expansion (hyperbola falling to the right), $BC$ is an isochoric pressure drop (vertical), $C D$ is an isothermal compression at the lower temperature, and $D A$ is an isochoric pressure rise. On the $P V$ plot this is a clockwise loop of two hyperbolas and two vertical lines. A.
